Hi, sometimes, like this morning, my 3 door refuses to start and displays a 1+1 (inductive REV/TPD sensor) error code more often than not, occasionaly 1+3 (ignition timing signal).

Since it normally started when I turned the ignition off and back on I ignored it up to now but I guess I should sort it out seeing it looks like it's not going to start until I do

I'm reasonably sure the two are related but can anyone confirm that the 1+1 relates to the crank sensor rather than the phase sensor?

CheeRS,
